This invention relates to arbors or spindles which will be. used in the cleaning and drying of roller stipplers by means of: centrifugal force. Thisdevice is, primarly mad to fit the, chuck of any high speed driving means suchas anelectric drill, or it may be used with any other small, suitable electric motor with a coupling on its shaft, to engage the spindle. Anobjectof the inventioniis to provide a means for quickly and easily attaching a roller stippler to'any quick revolving motor ordrill so that centrifugal force which is created by spinning the roller at high speed will throw ofiall soft paint and other liquids which are embedded :in the roller, after it hasbeenused.

Another object of this invention is to provide ameansof attaching any one of several sizesparticularly the length of roller stipplers to the same spindle. V a

A further object is the provision ,of a device for cleaning and drying roller stipplers, and for performing such other work, where the same spindle is employed, and which will be of such a durable nature, and extremely simple construction, that it may be used many times, and which may be manufactured and sold at a very low cost.

The invention possesses other novel features and advantages, which will be set forth in the following description and pointed out in the drawing, accompanying and forming a part of this specification. It will be understood, however, that variations may be made without departing from the scope of the invention, and the claims thereof.

Referring to the drawing,

Figure l is a view showing in elevation a spindle forming a part of my device.

Figure 2 is a top view of the spindle, as seen looking toward the supporting end thereof.

Figure 3 is a longitudinal section, and showing a long stippling roller locked in position on the spindle.

Figure 4 shows a similar view of the spindle with a short roller stippler locked on the spindle.

Figure dis a detail view, of a pin, for locking the roller on the spindle.

Figure 6 is a detail, of a compression spring, used to force the roller to its locked position against a stop and driver plate of the spindle.

Since the roller stipplers are not a part of my invention, I make no claim for their construction. I have drawn in section, as shown in Figs. 3 and 4, how they are mounted on the spindle, and are usually constructed of a tubular body portion of any suitable material such as wood, here indicated at- R, having at each end a recessed portion to form- 'a-shoulder---to receive a metal washer, indicated at RW,-the Zwasher's have a bore to fit slidably on the spindle, and the tubular body being covered bya suitable absorbing material, such as plush, andliere indicated by RC.

The spindle indicated at I, forming the main feature of-the invention, is made of suitable material, such as round drawn steel, orother suitable. metal, and is of such lengthto-support the longestof a series ofrollers, in common use.

:The supportingend C; of thespindle I is turned down to any suitable diameter, to readily fit a chuck, thereby leaving the remaining or 'body part of the spindle. on which the rollers are supported, by the washers. thereof, with proper size bores, at each end of'thexrollen- I The free end T, of the spindle. I, is also turned down, to form a shoulder, and this, a'short part,

is threaded, for useof any suitable tool, that may be driven by the spindle suchas an agitator. blade for mixing paint, 011 other ,tools. used by painters.

A series of holes are spaced along the body of the spindle and drilled thru the center and transversely of the axis of the spindle, at intervals, of about two inches along the spindle I, in the same plane, as indicated at H-4, H6, and H8 and a similar series of holes between the aforesaid series, but drilled at right angle thereto, and indicated at H-5, H-I, and H9, this being done so as not to weaken the spindle, in one direction, nor to throw it out of balance when driven at high speed, in other words, the spindle would flex more readily in one direction if the holes were all in one plane along the spindle. These holes are provided for a headed pin 4, which may be inserted in any one of the holes, to look a spring 3, in position against the outer end of any one of the rollers, (a. long or short one), as clearly shown in Figs, 3 and 4, the same spring 3, and pin 4, when the latter is placed in the proper hole, will serve to hold any one of the rollers under tension against the prongs P, of a stop plate and driver 2, forming a part of the spindle.

This driver plate 2, serving as a stop, is provided with prongs p, and is preferably formed of comparatively thin sheet metal, and is cut approximately, one and one quarter inch square, with a bore in its center, to fit snugly on the reduced supporting end 0, of the spindle, against the shoulder thereof, and may be welded or otherwise permanently fixed to the spindle, and the corners bent at right angle to form four teeth or prongs, as indicated at p, with the prongs 2 1 1 or points thereof, facing the free end of the spindle.

Variations may be made, and yet be invention.

When in use, the pin 4, is pushed into the holes to its head, the pin being of considerable length, will by centrifugal force tend to keep it in the shape of this stop plate 2, within the scope of this locked in place, and also the tension of the spring against the pin will prevent'itfrom .slipping out of the hole.

The operation of the device To clean a roller stippler, first clamp the sup'-.

porting end 0, of the spindle l, in chuckofielees tric drill, then slip a roller of any length, of the varying sizes, one end,

moved along the spindle, against the outer end of the roller, then push the spring by compressing the same tosuch a point, so the prongs p, of the driver will firmly engage the innerendof the roller and push the, pin, 4 into the hole most suitable to hold the spring under tension. To clean the roller stippler, first immerse the roller in paint solvent, such as benzene, varneline, etc., and allow spindle-to run for about twenty seconds,:next

remove rollerefrom solvent, and hold roller in empty pail or bucket,allowdrill to run, and r0,-

is permanently fixed, the pointed corners of to engage the'pronged driver plate 2, next the compression spring. 3 is cleaning and drying roller stip the spindle with successive which are bent to form prongs against which one end of the roller stippler engages, to be positively driven, means adjustable along the body of the spindle to force stipplers of various lengths against the prongs of the driver plate, including a series of perforations spaced along the body of perforations at a right angle to each other, a compression spring movable along the spindle to engage the other end of thed oller and held under tension by a headed pin at the rear of the spring in the perforation best suited to tension the spring, said pin being of suitable length to retain its position in the perforation by tension of the spring, and centrifugal action when the spindl is driven.

2. A spindle for use in cleaning and drying roller stippiers of various lengths, comprising a spindle of comparatively long length, reduced at one. end for attachment and. support thereof in a high speed driving means, and to form a shoulderat this end for permanent attachment of a prong'ecl' driver plate, said driver plate constructed of 'a sheet material to form a rectangular plate perforated at its center to fit said reduced end of: the spindle, and fixed to the shoulder of saidreduced end, as by welding, the pointed corners thereof, turned to form driving prongs adapted to engage one end and drive stippiers of various lengths, adjustable means to force any of the stippiers of various lengths to engage the driverprongs, including a series of spaced perforations bored along the body, of the spindle transversely of the axis thereof, and each perforation in order of their advance extending at a right angle to each other, a compression-spring following the roller on the spindle to engage the outer end of the roller to forcethe same against the driver prongs, a headed pin for insertion in the perforation most suitable to apply the proper tension to the spring to drive the roll with the spindle.
